DIG in plain words

Three months to Sep 30, 2026: DIG returned +33.5% where its own daily promise gave +35.7%, 2.2 points short. Read the multiple against the whole window instead and 2 times XLE's 17.2% implies +34.3%, which makes DIG look 0.8 points short. 1.4 of that is daily compounding, which happens to any 2 times fund over the same path, and the rest is the fund. DIG aims to return +2 times XLE's move each day, then resets. Over one day it does that. Over longer, the daily results compound, so the total is not +2 times the period's move: in a market that falls and comes back it is reliably less, and in a steady run it can be more. XLE moved at 21% annualized over that window. That is what decides how far the two figures separate: the same fund on a calm underlying and a violent one is a different product.

ERX in plain words

Three months to Sep 30, 2026: ERX returned +33.9% where its own daily promise gave +35.7%, 1.8 points short. Read the multiple against the whole window instead and 2 times XLE's 17.2% implies +34.3%, which makes ERX look 0.4 points short. ERX aims to return +2 times XLE's move each day, then resets.

Questions people ask

Which came closer to its stated multiple, DIG or ERX?
Over the window to Sep 30, 2026, DIG finished 0.8 points from what its multiple implies and ERX finished 0.4 points from its own, so ERX came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.
Are DIG and ERX levered on the same thing?
Yes. Both are levered on energy, DIG at +2 times and ERX at +2 times the daily move.
Which one decays faster, DIG or ERX?
Decay follows how much the underlying moves about. Over this window DIG’s moved at 21% annualized and ERX’s at 21%, so DIG has the rougher ride and, at the same multiple, loses more to compounding.
Can I hold DIG or ERX for a year?
Both reset every day, so the multiple in the name applies to a single day and the daily results compound. Over a year the total is not the multiple times the year’s move, and in a market that falls and comes back it is reliably less. ETFIQ makes no recommendation either way.
Which is cheaper, DIG or ERX?
DIG charges 0.95% a year and ERX charges 0.91%, so ERX is cheaper. Fees come from each fund's prospectus.
